Hi there !
I downloaded the highlighter package made available by Mark Hardwood on :
http://home.clara.net/markharwood/lucene/highlight.htm
I followed the instructions given on this site to use the package, but when I try to run my
application, I get the following message :
" Method rewrite(org.apache.lucene.index.IndexReader)
not found in class org.apache.lucene.search.Query.query = query.rewrite(reader); "
Then, if I remove the instruction "query = query.rewrite(reader);", I get another NoSuchMethodError
for org.apache.lucene.search.TermQuery.getTerm()
(A piece of my source code is at the end of this message)
Does anybody have a clue to solve my problem ?
And by the way, can somebody explain me what the query.rewrite() function is used for exactly
?
I thank you all in advance.
Alex.

IndexReader reader = IndexReader.open(indexName);
searcher = new IndexSearcher( reader );
Analyzer analyzer = new FrenchAnalyzer();
query = QueryParser.parse(queryString, "contents", analyzer);
query = query.rewrite(reader);
QueryHighlightExtractor highlighter =
new QueryHighlightExtractor(query, new FrenchAnalyzer(),
"<font style=\"background:yellow;\">", "</font>");
int highlightFragmentSizeInBytes = 80;
int maxNumFragmentsRequired = 4;
String fragmentSeparator="...";
String highlightedSummary =
highlighter.getBestFragments(summary, highlightFragmentSizeInBytes,
maxNumFragmentsRequired, fragmentSeparator);
For information, I added
C:\Projets\Lucene\lib\highlighter.jar
C:\Projets\Lucene\lib\lucene-1.3-final.jar
C:\Projets\Lucene\lib\lucene-demos-1.3-final.jar
to my classpath.
